Abstract: An arthroscopic system includes a re-useable, sterilizable handle integrated with a single umbilical cable or conduit. The single umbilical cable or conduit carries electrical power from a power and/or control console to the handle for operating both a motor drive unit within the handle and delivering the RF power to a disposable RF probe or cutter which may be detachably connected to the handle. The RF power delivered to the handle and on to the probe or cutter is typically bi-polar, where the handle includes first and second electrical bi-polar contacts that couple to corresponding bi-polar electrical contacts on a hub of the disposable RF probe or cutter is connected to the handle.

Abstract: A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A cutting member having a plurality of sharp edges is formed from a wear-resistant ceramic material is carried at the distal end of the elongated sleeve. A motor drive is coupled to the proximal end of the elongated sleeve to rotate the sleeve at cutting member at high RPMs to cut bone and other hard tissue. An electrode is carried in a distal portion of ceramic cutting member for RF ablation of tissue when the sleeve and cutting member are is a stationary position. In methods of use, (i) the ceramic member can be engaged against bone and then rotated at high speed to cut bone tissue, and (ii) the ceramic member can be held in a stationary (non-rotating) position to engage tissue and RF energy can be delivered to the electrode to create a plasma that ablates tissue.

Abstract: An arthroscopic or other medical device includes an elongate shaft having a proximal end and a working end. At least one electrode for treating tissue is located at the working end of the shaft, and a fluid outflow path extends proximally from the working end through a first channel portion in the shaft. A handpiece is coupled to the proximal end of the shaft and has a body with a second channel portion formed along an axis therein. The second channel is receives a heated or other outflow from a proximal end of the first channel in the shaft, and the second channel runs along an axis of the handpiece. A thin wall sleeve is located in the handpiece so that it surrounds at least a portion of the second channel. The thin wall sleeve is surrounded by an air gap or otherwise provides a thermal barrier between an exterior surface of the thin wall sleeve and an inner surface of the body of the handpiece in order to limit heat transfer from the heated or other fluid outflow through the second channel.

Abstract: An arthroscopy handpiece includes a handle body and a plurality of electrical components carried by the handle body. The electrical components may be connected to an external controller and power supply remote from the handle body. Typical electrical components include a motor and radiofrequency (RF) contacts adapted for coupling to a disposable electrosurgical tool. The handle body is usually both thermally and electrically conductive, and insulator elements are disposed between the electrical components and the handle body, with each insulator element adapted to prevent a potential leakage current flow from an electrical component to the handle body to prevent accidental electrical shock to the user.
